Wrj4P5

IRSensor functionarity
[note]
-length of irLights[] is always 4.
- when no light is, it's value is (-1, -1, -1)
- when IRMode'ir' is Wrj4P5.EX, it's value is (x, y, -1), default
- when IRMode'ir' is Wrj4P5.IR, it's value is (x, y, s)
*whre x:0to1, y:0to1, s:size. (origin is at Left-Bottom)
-If irMode'ir' is set to be Wrj4P5.IR, any extention is not available.
-Because I have no sensor bar and I have tested with a candle, the IRSensor test is limmited.

[changes]
- bug fix around irLights[]
- remove Wrj4P5(boolean irMode)
- add connect(boolean ir), connect(int n, boolean ir)
